In this paper, menstruation prescriptions were selected from "Fu Qingzhu's Obstetrics and Gynecology" and analyzed by using GRI algorithm, correlation analysis, hierarchical clustering method through SPSS, Clementine and traditional Chinese medicine (TCM) inheritance auxiliary systems, in order to screen out 15 menopathy prescriptions, which involve 45 traditional Chinese medicine herbs. In the study, blood-tonifying and qi-tonifying herbs were found to be frequent in the prescriptions. The most frequent single herb was white paeony root, accounting for 9.6% in the total number of prescriptions; The most frequent herb pairs were white paeony root-radix rehmanniae preparata and paeony root-angelica sinensis. Among Fu Shan's menopathy prescriptions, 61 herbal pairs showed a correlation coefficient exceeding 0.05, which evolved into 16 pairs of core combinations. The analysis showed that menopathy prescriptions in volume 1 of "Fu Qingzhu's Obstetrics and Gynecology" focused on tonic traditional Chinese medicines involving liver, spleen and kidney and were adjusted according to changes in qi, blood, cold, hot and wet, which could provide a specific reference for further studies on Fu Shan's academic thoughts and traditional Chinese medicine clinical treatment of menopathy.

Objective To observe the effect of Ti-6AL-4V particles on morphological and func- tional changes of osteoclast in vitro.Methods Mature osteoclasts separated from New Zealand Rabbits were cultured on glass slices and cortical bone slices.The experimental group was stimulated by Ti-6AL- 4V particles at concentration of 0.1 mg/ml.The cells were stained with TRAP at different culture time to observe the morphological variety.The bone resorption pits on bone slices were stained by toluidine blue and the resorption areas analyzed by computer image analysis software.Results Osteoclasts phagocy- tosed the particles,with irregular shapes,deeper TRAP stain and earlier apoptosis.Stimulation by Ti- 6AL-4V particles brought about larger area of bone absorption lacuna.Conclusion Osteoclasts have the ability to phagocytose Ti-6AL-4V particles,which leads to morphological and functional changes and enhances bone resorption.

OBJECTIVETo observe the effect of Jianpi Bushen Qingchang Huashi Recipe (JBQHR) on proliferation and migration of bone marrow mesenchymal stem cells (BMSCs).

METHODSBMSCs were isolated and cultured in vitro with adherence screening method to prepare cell suspension. No drug intervention was given to BMSCs in the vehicle control group. JBQHR at 0.39, 0.78, 1.56 µg/mL was added in BMSCs of low, mid, and high dose JBQHR groups for co-incubation. Its effect on the proliferation of BMSCs was detected by CCK-8. BMSCs migration and chemotactic ability was detected using Transwell method. Each dose JBQHR combined ERK kinase inhibitor U0126 was set up as control. The phosphorylation of extracellular regulated protein kinase (ERK) and CAMP responsive element-binding protein (CREB) were detected by Western blot.

RESULTSCompared with the vehicle control group, the proliferation of BMSCs and BMSCs migration number could be promoted in the 3 JBQHR groups (P < 0.05). Besides, the proliferation of BMSCs was better in mid and high dose JBQHR groups than in the low dose JBQHR group (P < 0.05). Compared with the vehicle control group, the phosphorylation of ERK and CREB could be elevated in the 3 JBQHR groups (P < 0.05), and could be inhibited by U0126 (P < 0.01). Compared with the low dose JBQHR group, the phosphorylation of ERK increased in mid and high dose JBQHR groups with statistical difference (P < 0.05).

CONCLUSIONJBQHR could promote the proliferation and migration of BMSCs, and its mechanism might be related to ERK/CREB signaling pathway

BACKGROUND: Hippocampus is an important region involved in learning and memory. Some methods for freshly isolated hippocampal pyramidal neurons have been described. These methods need multiple enzymes or the procedure is complex.OBJECTIVE: To acquire large quantities of hippocampal neurons from rats suitable for patch clamp study.DESIGN: An animal experimental observation.SETTING: Department of Physiology and Pathophysiology, School of Medicine, Xi'an Jiao Tong University.MATERIALS: The experiments were carried out in the Medical Experimental Center, School of Medicine, Xi'an Jiao Tong University between March and October 2004. The animals were the 10-15-day-old SpragueDawley rats, bothmale and female.METHODS: Hippocampal pyramidal neurons were freshly isolated. Delayed rectifier potassium current and voltage-gated Ca2 + currents were recorded by whole-cell patch clamp configuration.MAIN OUTCOME MEASURES: Acute isolated neurons were observed with a Leica microscope. Recordings of delayed rectifier potassium currents and voltage-gated Ca2+ currents were obtained.RESULTS: ① Under the inverted microscope, the acute isolated neurons had a smooth and glassy surface, a three-dimensional contour, a pyramidal shape with a longer apical dendrite and several basal dendrites. ② After the whole cell recording configuration was formed, voltage-gated barium currents through calcium channels were elicited by 200 ms depolarizing potential from -70 mV to +20 mV, with an increment of 10 mV, a holding potential was -90 mV. Delayed rectifier potassium current (Ikd) was elicited by a protocol consisting of a multiple depolarizing pulses (-60 mV to +50 mV),preceded by a single prepulse step to -50 rmV, with inactivated transient outward potassium currents from a holding potential of -80 mV.CONCLUSION: This method is simple and ideal for the dissociation of neurons from rat hippocampus, and offers a powerful tool for functional analysis of ion channels by patch clamp.

Objective To evaluate biodistribution and pharmacokinetics pattern of ~(131)I-labeled rch24which is the region-grafted (humanized) anti-carcinoembryonic antigen (CEA) monoclonal antibody in nude mice. Methods Nude mice bearing cancer xenografts received intravenous injections of ~(131)I- rch24, then blood, plasma, heart, liver, spleen, lung, kidney, tumor and other tissues were taken at different time point for determination the concentration of radioactivity and calculate the T/NT value. Nude mice were packeted randomly to four group of high, medium, low dose and continuous administration, blood drug concentration was detected by ELISA method at the different intervals. Then, draw the concentration-time curve and calculate the pharmacokinetics paramete. Results After administration, radioactivity of the tumour was significantly enhanced whereas radioactivity of normal tissues decreased gradually. For single administration, at the dose of low to medium, pharmacokinetics pattern was linearity -kinetics whereas for high dose group,pharmacokinetics paramete shown some behavior of non-linearity-kinetics. Conclusion Our results suggest that the ~(131)I-labeled region-grafted (humanized) anti-CEA monoclonal antibody rch24 exhibit a considerable targeting activity so as to ~(131)I radioisotopes can be concentrated specifically in tumor. The pharmacokinetics pattern of this medicine was different at different dose.

AIM:To investigate the safety and effect of femtosecond laser-assisted cataract surgery with Cionni modified capsular tension ring (MCTR) implantation in the management of traumatic lens subluxation.METHODS: Totally 11 patients (11 eyes) with traumatic lens subluxation were divided into three groups according to the severity of lens dislocation, ranging from 90° to 120° (4 eyes), 120° to 180° (5 eyes) and 180° to 270° (2 eyes).The contact LenSx femtosecond laser cataract surgery platform was applied to create the capsulotomy, prepare nuclear fragmentation and make corneal wound creation.Anterior vitrectomy was performed in some patients during the surgery.After capsular retractors insertion and phacoemulsification, the MCTR was inserted to the capsular bag and fixed to the sclera.Finally, the IOL was implanted into the capsular bag.Postoperative visual acuity, intra-and post-operative complications, anterior capsular opening, IOL and MCTR position and intraocular pressure (IOP) were assessed.RESULTS:The duration of follow-up was 2mo.All the operations were completed successfully.Five eyes underwent cataract surgery combined with anterior vitrectomy.Four eyes had been inserted with 2-eyelet MCTR and seven eyes with 1-eyelet MCTR.The best corrected visual acuity (BCVA) after operation was better than 0.5 in 4 eyes, between 0.3 and 0.5 in 3 eyes, between 0.1 and 0.3 in 3 eyes, and less than 0.1 in 1 eye.Compared with preoperative BCVA, the difference was statistically significant (P<0.05).All the IOLs were stably centered and the eyelet of MCTR was fixated steadily between the iris and the anterior capsule.The common intra-and post-operative complications were subconjunctival hemorrhage, incomplete capsulotomy, residual cortex, secondary glaucoma and posterior capsular opacification.CONCLUSION:Femtosecond laser-assisted cataract surgery can improve the success rate of capsulorhexis, and reduce the difficulty of nuclear fragmentation.Femtosecond laser-assisted cataract surgery combined with MCTR implantation is an ideal surgical method for traumatic lens subluxation.

In order to investigate the expression of nerve growth factor (NGF) and hypoxia inducible factor-1α (HIF-1α) and its correlation with angiogenesis in non-small cell lung cancer (NSCLC), paraffin-embedded tissue blocks from 20 patients with NSCLC were examined. Twenty corresponding para-cancerous lung tissue specimens were obtained to serve as a control. The expression of NGF, HIF-1α, and vascular endothelial growth factor (VEGF) in the NSCLC tissues was detected by using immunohistochemistry. The microvascular density (MVD) was determined by CD31 staining. The results showed that the expression levels of NGF, HIF-1α and VEGF in the NSCLC tissues were remarkably higher than those in the para-cancerous lung tissues (P<0.05). There was significant difference in the MVD between the NSCLC tissues (9.19±1.43) and para-cancerous lung tissues (2.23±1.19) (P<0.05). There were positive correlations between NGF and VEGF, between HIF-1α and VEGF, and between NGF and HIF-1α in NSCLC tissues, with the spearman correlation coefficient being 0.588, 0.519 and 0.588, respectively. In NSCLC tissues, the MVD had a positive correlation with the three factors (P<0.05). Theses results suggest that NGF and HIF-1α are synergically involved in the angiogenesis of NSCLC.

OBJECTIVETo assess the morphologic changes in traumatic cerebral infarction and to discuss its mechanism.

METHODSSpecimens from seventeen cases of cerebral infarction were selected from 81 patients with severe brain injury, and subject to routine gross and histological examinations.

RESULTS(1) The cerebral infarction in all cases was hemorrhagic in nature with a wedged or irregular shape upon gross inspection. The lesions were found in occipital gyrus (8 cases), occipital lobes (3 cases), basal nuclei (3 cases), cingulate gyrus (2 cases), and lateral occipitotemporal gyrus (1 case). Histologically, the lesions were located at the junction between the cortex and medulla, showing congestion, edema, hemorrhage, necrotic nerve tissue and blood vessels. In severe cases, the lesion extended into the entire cortex and subarachnoid spaces. (2) Swelling of the brain and cerebral hernia were found in all cases, 8 of which demonstrated that the posterior cerebral artery was compressed and stenotic within the space between the crus cerebri and uncus.

CONCLUSIONBrain tissue necrosis in traumatic cerebral infarction is the result of brain swelling and cerebral hernia formation, following congestion, bleeding and ischemia due to vasculature compression.
